Solar Hot Water Space Heating Systems
SUNDOG SOLAR offers award winning WAGNER SOLAR HEATING SYSTEMS
The unique Solar Combi tank offers an efficient SOLAR-POWER HOME HEATING package that includes a 2 in 1 domestic
hot water storage and buffer tank utilizing solar energy for both SOLAR HOT WATER preparation and SPACE HEATING
support.
HOW DOES IT WORK?

The top 1/3 of the tank is reserved for the domestic hot water needs of the home. As the middle of the
tank temperature reaches 110 degrees, the system controller will open the three way diverter valve allowing the
water in the tank to circulate through a low temperature heating system
such as radiant floor loops or a *low temperature baseboard system. Once the middle of tank temperature drops
below 110 degrees, the system controller closes the three way diverter valve allowing the traditional heating
system to take on the home heating duty.
*Traditional baseboard heating systems require higher temperatures in the 160 degree range and would deplete the
excess heat in the Combi tank too quickly for it to be effective.
